MULTI-STORIED LANDSLIDES AND STRENGTH OF SOFT CLAYS

SLIDING OF SOME SLOPES PROCEEDS IN SEVERAL LEVELS LOCATED ONE ABOVE ANOTHER; THESE MOVEMENTS MAY BE OF DIFFERENT TYPE AND PROCEED ALONG DIVERGENT TRAJECTORIES WITH DISSIMILAR RATES. THE RESOLUTION OF VECTORS OF RATES OF DISPLACEMENT OF SURFACE BENCHMARKS AND THE DETERMINATION OF OUTLINES OF DIFFERENT LEVELS OF SLIDING MAY BE MADE GRAPHICALLY, TAKING INTO ACCOUNT THE TYPE AND DISTRIBUTION OF LANDSLIDE FISSURES, DEFORMATION OF CONSTRUCTIONS AND GEOLOGICAL CONDITIONS. THE EXPERIMENTS HAVE SHOWN THAT THE RESIDUAL SHEAR STRENGTH IS ALMOST THE SAME FOR CLAYS OF DIFFERENT TYPE AND ORIGIN AND COINCIDES WELL WITH THE AVERAGE SHEAR STRENGTH CALCULATED FROM THE SLIDE DATA ALONG THE ACTUAL SURFACES OF SLIDING. THE GRADUAL ALTERATION OF CLAY PARTICLES ORIENTATION PROCEEDS BY DEFORMATION OF SOIL. THE SHEAR DIAGRAM IN TERMS OF OCTAHEDRAL EFFECTIVE STRESSES IS THE SAME FOR DIFFERENT TEST CONDITIONS AND INITIAL STATE OF CLAYS. /AUTHOR/
